As a high number of our clients have puppies or dogs between 2 and 18months old, we thought we might shine a bit more light on what’s going on.

Just to clarify one often asked question; dogs older than 18months can certainly be trained, we have successfully trained dogs up to 12 years old.

To get started, the first 18 months of a dog’s life are crucial for their overall development and well-being. It is during this time that they undergo significant physical, social, and cognitive changes that lay the foundation for their future behaviour and temperament. It is said that you get your “fully grown” dog after three years.

First year is physical maturity, Second year is mental maturity and Third year is emotional/social maturity.  

Overview of key developmental stages

The developmental stages in a dog’s life can be divided into distinct periods, each with its own set of milestones.

These stages include the neonatal stage (birth to 8 weeks), the early socialisation period (8 weeks to 4 months), adolescence (4 months to 8 months), continued development (8 months to 12 months), and the transition to adulthood (12 months to 18 months).

Birth to 8 Weeks

Neonatal stage: Development and dependency on mother

During the neonatal stage, puppies are highly dependent on their mother for warmth, nourishment, and socialisation. They spend most of their time sleeping and growing, relying on their mother’s care to develop basic bodily functions and motor skills.

Socialisation with littermates and early interactions

Interactions with littermates play a crucial role in a puppy’s social development. They learn important skills like bite inhibition, communication, and body language through play and exploration. These early interactions shape their ability to interact appropriately with other dogs later in life.

Introduction to basic senses and motor skills

As puppies grow, they start to explore their surroundings, using their senses to understand the world around them. They develop their sense of smell, sight, hearing, and touch. Additionally, they begin to develop coordination and basic motor skills like walking, running, and play-fighting.

Importance of a stable and nurturing environment

A stable and nurturing environment during this stage is crucial for a puppy’s overall well-being. They need a clean and comfortable living space, proper nutrition, and regular veterinary care to ensure healthy growth. Positive human interactions and gentle handling help build trust and confidence in humans.

8 Weeks to 4 Months

Transition to a new home and bonding with the owner

At around 8 weeks, puppies are ready to leave their littermates and transition to their new homes. This period is crucial for building a strong bond between the puppy and their new owner. It is important to provide a secure and loving environment to ease the transition and help the puppy feel safe.

Early training and basic obedience commands

Basic training should commence during this stage. Puppies can learn simple core commands such as sit, stay, and come when called.

Proper techniques focusing on relationship building should be used to encourage desired behaviours and establish a foundation for future training.

Introduction to crate training and housebreaking

Crate training and housebreaking are important aspects of a puppy’s development. Introducing them to a crate helps create a safe space and assists with housebreaking. Consistency, patience, and leadership are key when teaching puppies toilet training and to go in appropriate areas.

Teething and appropriate chew toy selection

Between 4 and 6 months, puppies start teething, which can be a challenging phase. Providing appropriate chew toys helps alleviate discomfort and prevents destructive chewing on household items. Ensuring a variety of textures and sizes will cater to their changing needs as they lose their baby teeth.

Adolescence and the onset of puberty

During this stage, puppies go through adolescence, which is similar to the teenage phase in humans. They experience hormonal changes and may exhibit behaviour challenges, such as increased independence or testing boundaries. Consistent training and guidance are essential to navigate this stage successfully. This time also marks the end of Puppyhood.

Continued socialization with other dogs and people

Socialisation remains crucial during this period. Continued exposure to a variety of dogs, people, and environments helps puppies develop good social skills and reduces the likelihood of fear or aggression towards unfamiliar situations. Arranging playdates with other well-behaved dogs can provide valuable socialisation opportunities.

8 Months to 12 Months

Continued physical and mental development

During this stage, dogs continue to grow physically and mentally. Regular exercise and mental stimulation are essential to keep them physically fit and mentally engaged. Activities like walks, interactive play sessions with trusted other dogs, and puzzle toys can help meet their energy and mental stimulation needs.

Importance of regular exercise and playtime

Providing young dogs with regular exercise and playtime is crucial for their physical and mental well-being. Engaging in activities that match their individual energy levels not only helps burn off excess energy but also strengthens the bond between the owner and the dog.

12 Months to 18 Months

Transition from Adolesce to adulthood

Around 12 months, puppies start transitioning from Adolescence to Adulthood. They may become more settled in their behaviour and develop a more predictable routine. However, they still require continued guidance, training, and socialisation to become well-adjusted adult dogs.

Sexual maturity and considerations for spaying/neutering

During this stage, some dogs may reach sexual maturity. It is important for owners to consider spaying or de-sexing their dogs to prevent unwanted litters and reduce the risk of certain health issues. Consultation with a veterinarian can provide guidance on the appropriate timing for this procedure.

Fine-tuning obedience and addressing behaviour challenges

As dogs approach adulthood, it is essential to continue reinforcing good behaviour and addressing any lingering behaviour challenges. Consistency, leadership, and patience remain key to refining obedience and ensuring a well-behaved dog.

Monitoring overall health and addressing any emerging issues

Regular veterinary check-ups are crucial during this stage to monitor the dog’s overall health and well-being. Vaccinations, parasite prevention, and dental care should be maintained. Owners should also be observant of any emerging health issues or changes in behaviour and seek professional advice as needed.

Recap of key developmental milestones in the first 18 months

The first 18 months of a dog’s life are filled with significant milestones and developmental stages. From their early dependence on the mother to their transition into adulthood, each phase plays a crucial role in shaping their behaviour, socialisation, and overall well-being.

Investing time and effort in the first 18 months of a dog’s life yields long-term benefits. A well-rounded and well-adjusted adult dog is more likely to have good social skills, be obedient, and form strong bonds with their owners. This sets the stage for a fulfilling and harmonious lifelong relationship.

Responsible dog ownership involves understanding and meeting the needs of a growing puppy throughout their first 18 months. Providing a loving, nurturing environment, proper training, socialisation, and veterinary care contribute to the well-being and happiness of both the dog and their owner.
